May 12, 1936. H. FABRY PHOTOGRAPH DISPLAY APPARATUS Filed Dec. 20, 1935 PHO TO GRH PH Patented May 12, 1936 UNITED STATES PATENT OFFICE Application. is?! No. 55,337

My invention relates to means for displaying photographs and similar illustrations and particularly to an improvement on or modification of the construction illustrated in my copending application, Serial No. 21,090, filed May 13, 1935.

In the construction heretofore proposed and illustrated in my said copending application, the photographs or illustrations are joined back-toback with a hinge member at one side edge within which a resilient wire is mounted, the wire and photographs being adapted to be bowed in order to insert the projecting ends of the wire into openings in adjacent parallel flanges or walls that are fixed to a support. This construction is useful and satisfactory, but I have found that a desirable result may be secured in another manner by providing a transparent envelope within which the photographs may be placed, either singly or in back-to-back arrangement, the envelope being provided with a hinge member preferably in the form of a spiral tube within which the said wire may be seated. This construction enables withdrawal or substitution of photographs and adapts the device for use without the neces- 2 sity for adhesively joining photographs to a hinge member previous .to use.

The invention will be more readily understood 113; rglalference to the accompanying drawing, in w z Fig. lisaplanviewofacarryingcaseor port folio to which my improved display apparatus has been applied; v 1

Fig. 2 is an end view, greatly enlarged, showing the assembly of the envelope, binding, tube,

"# wire, and photographs;

Fig. 3 is an enlarged sectionalview on-the line 3-3 of Fig. 1;

Pig. 4. is a fragmentary sectional view showing the position of the parts when mounted; and, Fig. 5 is a view, somewhat enlarged, show n the display unit separate from the carrying frame.

In the drawing I have illustrated a folder Ill on which a support II is mounted. Secured to the support are channels |2l 3 spaced apart in parallel arrangement, the inside walls or flanges "-15 of the channels being provided with a plurality of longitudinally spaced apertures It, as best shown in Fig. 4.

An envelope I1 is formed by doubling a sheet ct transparent material on itself, thus leaving open the two ends and one side. The open side is perforated as shown and a spiral tube It is caused to engage with the openings. This is gen- ,erally known as a spiral binding. Preferably the transparent material is a clear grade of a non-inflammable material such as used for some photographic films, although celluloid, Cellophane or similar material may be used.

The spiral tube accommodates a length of straight resilient wire l9\of greater length than 5 the length'of the envelope and of greater length than the space between the walls "-15. Thus, to enable the wire to be seated in the position shown in Fig. 3, it and the spiral tube and envelope, together with the photographs, if any are 10 in place, must be bowed as shown in dotted lines in Fig. 3. This-permits the two ends of the wire to enter the apertures IS in the walls. Thereafter the envelopes may be turned to either of two positions to display photographs that are received 15 through the open ends and placed back-to-back within said envelopes. Two photographs, indicated at 20--2l in Fig. 2, are shown in place, and

due to the relative stifiness of the material composing the envelope and the fact that normally 20 the envelopes-will be under some pressure, the photographs will remain flat without being joined back-to-back.

It is obvious that different forms of binge members may be substituted forthe spiral binding 25 shown, although I consider the said spiral binding as preferable. Thisand other modifications may be made without departure from the spirit of my invention. I

Iclaim:

1. In combination, a support, a pair of parallel spaced flanges perpendicularly arranged on said support, said flanges having a plurality of spaced transverse apertures, a transparent envelope adapted to receive a photograph, hinge means at 35 one side edge of said envelope, a wire in said hinge means, said wire being longer than the space between said flanges, said envelope, photograph, hinge and wire being adapted to be bowed in order to insert the ends of the wire in the apertures in said flanges.

2. In combination, a pair of parallel, spaced walls each having longitudinally spaced transverse openings therein, a transparent envelope adapted to receive two photographs in back-to-back relation, a wire connected to one side edge of said envelope, said wire being longer than the space between said walls, and projecting beyond the ends oi said envelope, whereby said wire and envelope must be bowed in order to insert the ends 'of said wire in the openings in said walls.

3. In combination, a pair of parallel spaced walls each having longitudinally spaced transverse openings therein, a transparent envelope adapted to receive a photograph, a spirally wou 55 tube of wire, the spirals of which engage one edge oi said envelope, a length of wire in said tube, said wire being of greater length than the space between said walls and projecting beyond the ends 'of said envelope whereby said wire must be bowed in order to be inserted in the openings in said walls. 7

s. In combination, a pair of parallel spaced walls each having longitudinally. spaced transverse openings therein, a transparent envelope" composed of a sheet of material doubled on itself and having open ends, a spirally wound tube of wire the spirals of which engage one edge of said envelope, a length 0! wire in saidtube, said wire being of greater length than the space between said walls and projecting beyond the ends of said envelope whereby said wire must be bowed in order to be inserted in the openings in said walls.

5. In combination, a pair-of parallel spaced walls each having longitudinally spaced transverse openings-therein, a transparent envelope composed of a sheet of material doubled on itself and having open ends, a spirally wound tube of wire, respective turns of which engage in openings in a side edge of said envelope, a length oi resilient wire in said spiral tube, said wire being of greater length than the space between said walls, whereby said wire and said spiral must be bowed in order to engage both ends of said wire in said walls.

6. In combination, a pair of parallel spaced the projecting ends of said wire being adapted acs aer I each having longitudinally spaced transverse openings therein, a transparent envelope composed 01 a sheet of material doubled on itself and having open ends, a spirally wound tube of wire, respective turns of which engage in openings in the otherwise open side oi said envelope, a length of resilient wire in said spiral tube said wire being of greater length than the space beto be received in openings in said walls;

8. In combination, a pair of parallel spaced walls, a transparent envelope composed of a sheet or material doubled on itseli! and having open ends, aspirally wound tube of wire, respective trans of which engage in openings in the otherwise open side oi. said envelope, a length 01' resilient wire in said spiral tube, said wire being of greater length than the space between said walls, the projecting ends of said wire being 30 adapted to be received in openings in said walls.
